cerebrum-news-corpus
Frozen, reproducible historical news corpus for cerebrum's LLMNewsBrain
(Track 3, Phase 3.4). One row per (ticker, article), with columns matching
cerebrum.source_protocols.events.NewsEvent exactly so cerebrum can rehydrate
NewsEvent instances 1:1. Built by TradingDataScraper
(scripts/build_news_corpus.py) from GDELT GKG 2.1 via BigQuery
(gdelt-bq.gdeltv2.gkg_partitioned). The cerebrum library never fetches live; it
reads this snapshot via a CachedNewsEventSource — mirroring how
CachedMacroFactorSource reads the committed FRED macro snapshot.

Universe
cerebrum-eval30 — the 30 large caps in cerebrum's
examples/eval_tft_cross_sectional.py::UNIVERSE.
Coverage caveat (important)
GDELT GKG's <PAGE_TITLE> (the only headline source in GKG) begins
~2019-09-22. No article headlines exist in GKG before then, so although the
original request targeted 2015, this corpus effectively spans
2019-09-22 → 2024-12-31 (~5.25 years, the 2019 shard is Q4 only).
Language
language_mode = all-original: headlines are kept in their original
language (≈¼ are non-English), not translated. The builder also supports
--language english and --language translate.
Matching
Tickers are assigned by case-insensitive substring match of curated company-name
terms (seeded from SEC company_tickers.json, tuned to GDELT's V2Organizations
rendering) — see ticker_terms in the manifest. Approximate by design and kept
raw per the NewsEvent Protocol boundary; cerebrum computes its own labels.
Precision filter applied. This corpus keeps only articles carrying an
economic/business GDELT theme (V2Themes matching ECON_|BUS_|EPU_ECONOMY; see
manifest theme_regex), dropping ~47% of raw org matches (the tangential tail —
companies merely name-dropped in unrelated stories). ~6.67M rows.
